(The top 5 teams are Clemson, ND, Miami, UNC, and VT.)

Teams playing four of the top five
FSU: Miami, ND, UNC, Clemson

Teams playing three of the top five:
BC: VT, Clemson, ND
Clemson: Miami, ND, VT

Notre Dame only plays two of the top five:
ND: Clemson, UNC

I don't know how Notre Dame managed to get a creampuff schedule (or who would have known FSU and Loserville would be unexpectedly bad), but there are 9 teams with 2 or more losses in the ACC and Notre Dame plays 8 of them.
